I'm in the middle of watching this and after the part starting at 22:31 with Robert M. Price, I realized that "Satan" has actually been one of Christianity's biggest allies. Something doesn't fit the Bible? Oh, it's just a deception by Satan. Live by a set of different rules than us? Satan will have you burn in hell for all eternity. Christians may not realize it, but perhaps they owe a lot to this "Satan" figure.
